The best way to prevent illness is to avoid being exposed to or spreading the virus that causes COVID-19:
- Wash your hands often.
- Avoid close contact with people who are sick and people who don’t live in your household.
- Cover your mouth and nose with a mask when around others.
- Cover your coughs and sneezes.
- Clean and disinfect frequently touched surfaces.
- Monitor your health daily.
Getting a flu vaccine is more important than ever this flu season to protect yourself, your family and your community from flu. A flu vaccine can also help reduce the burden on our healthcare systems responding to the COVID-19 pandemic and save medical resources for care of COVID-19 patients.
If you think you may have been exposed to a person with COVID-19, contact your healthcare provider.
- Stay home and away from the people you live with as much as possible.
- Consider getting tested.
- Monitor your symptoms.
- If you show an emergency warning sign, seek emergency medical care immediately. Call 911 or call ahead to your local emergency facility. Emergency warning signs include:
- Trouble breathing
- Persistent pain or pressure in the chest
- New confusion
- Inability to wake or stay awake
- Bluish lips or face.
The FDA can issue emergency use authorizationexternal icons (EUAs) to allow healthcare providers to use products that are not yet approved, or that are approved for other uses, to treat patients with COVID-19 if certain legal requirements are met.
Any treatments that are used for COVID-19 should be taken under the care of a healthcare provider.
The National Institutes of Health (NIH) has developed and regularly updates Treatment Guidelinesexternal icon to help guide healthcare providers caring for patients with COVID-19, including when clinicians might consider using one of the products under an EUA. Currently, there are several approaches for treating patients with severe COVID-19 who are being cared for in the hospital. In studies, some drugs have shown some benefit in reducing the severity of illness or risk of death by:
- Slowing the virus. Antiviral medications reduce the ability of the virus to multiply and spread through the body.
- Reducing an overactive immune response. In patients with severe COVID-19, the body’s immune system may overreact to the threat of the virus. This can cause damage to the body’s organs and tissues. Some treatments can help reduce an overactive immune response that worsens the disease.
- Dexamethasoneexternal icon is a steroid medication, similar to a natural hormone produced by the body. The NIH Treatment Guidelinesexternal icon recommend dexamethasone, or a similar medication, for some hospitalized patients with severe COVID-19 to prevent or reduce injury to the body. Dexamethasone is recommended for patients who need supplemental oxygen.
- Treating complications. The virus that causes COVID-19 can damage the heart, blood vessels, kidneys, brain, skin, eyes, and gastrointestinal organs. It also can cause other complications. Depending on the complications, additional treatments might be used for severely ill hospitalized patients, such as blood thinners to prevent or treat blood clots.
- Supporting the body’s immune function. Antibodies from patients who have recovered from COVID-19 (convalescent plasma) or antibodies manufactured for COVID-19 (like monoclonal antibodies) can attach to parts of the virus. This could help the immune system recognize and respond more effectively to the virus, but currently the NIH Treatment Guidelinesexternal icon find there is not enough evidence to recommend these treatments.
- Relieving symptoms and supporting the body’s natural defenses.
- Taking medications, like acetaminophen or ibuprofen, can reduce fever.
- Drinking or receiving intravenous fluids can help patients stay hydrated.
- Getting plenty of rest can help the body fight the virus.
Other products are being studied as potential treatments for COVID-19. Information about these ongoing studies can be found at ClinicalTrials.govexternal icon.
